WHEEL FOR STEAM-FLOWS AND THE LIKE Locaties.

Specification of Letters Patent.

Patent-ed 1 u1 y 29, 1913.

Application led May 14, 1909. Serial No. 496,049.

of illinois, have invented certain new and useful Improvements in aivheel for Steam- PloWs and the Like, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to improvenients 1n ground Wheels adapted for useon steam plows or other machines of like character.

The objects of the inyention are to provide a Wheel of this type, strongand simple in construction and having improved means for lubrication.

Other objects Will appear inthe following specification.

Of the drawings, Figure l is a side view of a wheel embodying myinvention. The left hand portion of the Wheel is shown in cross sectionalong the line wof Fig. 2. Fig. 2 is a cross sectional elevation of the.Wheel along the line y-g/ of Fig. A1. -Fig. 3 is aside view showing'thesupport for the ivheel. Fig. 4 is a fragmentary cross see,- tional viewof one of the side plates and shows a hand hole plate, in position.

Referring to the drawings, 1, 1 are supporting boxes and are mountedupon the of the plow or other machine.

3 is a. circular shaft or axle rigidly mounted in the boxes 1, 1.

4, 4 'are circular side plates and are formed, preferably, integrallywith the inl Wa rd extending hubs 5, 5. These hubs are bored to receivethe shaft 3 and to turn upon it with a good running fit. The inner endsof the hubs 5, 5 are turned to such a size that they will enter the castiron ring 6 With Zw-7 represent a series of pockets formed in lhezsideplates at points near the outer peripherics The holes S- are drilled atthe bottom of,these pockets to receive the threarled tic-rods 9-9. Thesetie-rods are provided with nuts at cach end, by :means of which the ttvoside piates may be drawn toward cach other.

10---10 are flat ribs extending radially from the hubs 5. 5 and arepreferably located in the same planes with the pockets 7-7 and thetie-,bollts'Q-Q.- These ribs are preferably Wider` at: their-Timer endsthan at. their outer ends and are so proportioned that they will act aseantaliver beams of approximately uniform strength.

11-11 represent a series of supplementary pockets. similar `to thepockets 7--7. These are formed as close as practical to the hubs and arepreferably located between each alternate pair of the ribs 10, 10. Theyare provided With tie bolts 12H12, similar to the tie bolts 9 9.-

The side plates f4 have peripheral grooves or notches 13, loadaptcd toreceive the tire 14. The tire is preferably formed of a single piece ofsheet steel. I n the draW- ings I have shown this tire as having itsends joined at 15 by means of the butt-strap 16, to which the ends areriveted. The grooves 13, 13 are provided withl recesses 17. 17 toreceive the butt-strap 16, and by its engagement with the sides of theserecesses the buttstrap serves as a key to prcvent the rotation of thetire relative tothe side plates. lf preferred7 however, the tire may herelied into a continuous band from a single piece of metal. In thiscase, the butt-strap 16 and the recesses 17, 17 would ofcourse. beunnecessary.

The side plates are provided with the laterally extending collars 18,18. These collars serve to receive any end thrust ofthe wheel againstthe boxes and also serve to deflect the dirt and rubbish away from thepoint where the shaft emerges from the Wheel.

Each of the hubs 5, 5 is provided with an oil or grease chamber 19.' Anysuitable means for supplying oil or grease to this chamber may be used.For purposes. of illustration, however, I have shown a pressure greasecup Q0, connected to each cham ber by means of the oil hole 21. plate4A, t is provided with a hand hole 22. the two hand holes beingpreferably located on opposite. sides of thcaxis of thc wheel.

23, Q3 are hand hole covers adapted to tightly close the hand holes.These covers are held in place by the vokes Q4. 2t and thc bolts 25. Q5.In this way, the space \\itliintlie wheel is entirely inclosed land nodust or dirt can enter. When it is necessary to obtain access to theinterior of the Wheel to replenish the'supply of lubricant or to adjustthe lubricating devices, this may be readily done by removing whicheverof the hand hole covers is uppermost. The lubrillach side eating devicesare preferably located in a plane at an angle to theplane of the handholes in order that they may be reached equally well from either handhole.

In constructing` and assembling, the ring 64 -should preferably beforced in place over one of the hubs, the tire then placed in' position,and the other hub then4 forced into the ring 6, the corresponding sideplate being thus: brought into engagement with the tire. The tie-rods9-9 and l1--l1 may' thenl be put in place and the nuts tightened. The

- whole wheel will thus be securely clamped together. The holes throughthe hubs for the shaft 3 should preferably not be bored until after thewheel-is assembled. This will insure perfect alinement of the holesthrough the two hubs, and any subsequent displacement is made impossibleby theA ring 6.

What I claim isl.V In a Wheel, two side members each having an inwardlyextending hub and bracing ribs, a tire between the side members and tierods for clamping the side members in position relative to the tire,each tie rod being located in the plane of a rib substantially as setforth.

2. I-n a wheel, a tire formed with a buttmemes strap joint and two sidemembers each having a groove to receive the tire, and'each havinga-recess to receive the butt-strap, the

sides of the recess engaging rthe butt-strap to prevent the rotation ofthe tire relative to the side members, substantially as set forth.

3. In a Wheel, the combination of atire, two side plates each having ahand hole, the

hand holes being located at opposite sides 1 I of the wheel axis, coversfor the hand holes, and lubricating means for the axle bearing of thewheel located at a oint within the .wheel substantially equi-distantfromv the hand holes whereby 'it can be reached equally well from eitherhand hole, substantially` as Set forth.

4. In a Wheel, two separate sections each having a hub with a bearingaperture, a tire clamped between the two sections, and a ringsupplemental tothe tire engaging the hub for holding the bearingapertures in alinement, substantially as set forth.

In testimony whereof I affix my signature, in presence of two witnesses.
